Default M57: Ring Nebula in H-alpha + Luminance

Hi all,

I hope you'll like this new image of the nebula M57 obtained from two
different
series of shots in H-Alpha and luminance.

http://www.danilopivato.com/tabulae_...m57_brc_ha.htm

With three minutes of exposure to frame luminance was possible to capture
about 40
faint galaxies all clustered in an area of 16'x16 'centered on M57.

Of these faint galaxies could not find the name and magnitude with the
exception
of IC 1296.
On the map I have, however, reported their position and apparent shape:

Kind regards,
Danilo Pivato

Oh yes, I like very much! Maybe it's just my eyes but I had a sense of
depth with this one, a feeling of just how vast is the area covered by
that one little photo...

Very nice indeed, Danilo!
